Application(s): E-flite Ultimate 3D

Comments: I bought 4 of DSP75. All of them have centering issues; they are constantly searching for centers and causing control surfaces to vibrate like crazy. You have to decrease the loads for the servos or dampen the servo motions by using light rubber bands around the servo. Seriously, specktrum knows this issues. Just google Spektrum SPMDSP75 oscillation problem. I hope they still have the page online.
I don't know if i should risk my Ultimate 3D for a test flight.

Application(s): throttle on a 60 size airplane

Comments: installed for a max of 4 hours. no flying thank goodness
just setting up and testing the engine. It froze up solid.
It always made noises like it wouldn't stop seeking. Had another new one. Just plugged it in the receiver to test and same noises and seeking. Didn't install the second one for fear it would freeze up too. They are going back. I consider them JUNK !
